From Hawaiian Libertarian:
“Food is grown, raised, harvested and processed — and if not consumed while fresh — preserved in as natural and organic a state as possible to keep most of it’s nutritious and nourishing qualities intact.
Feed is mass produced by a few large multinational corporations line using bio-technological innovations to quickly and efficiently manufacture product units ready for global distribution and a near infinite shelf life. Its primary traits are using genetically modified grain products to create a marketable product that is usually adulterated with preservatives and flavor enhancements that give it a long shelf life in airtight packaging and designed in a laboratory to stimulate the taste buds to fool the human body into thinking it’s something good for you.
But above all, the primary difference between Food and Feed can be discerned by this: most real food requires little (if any) corporate mass media marketing campaigns to sell product and expand market shares and waistlines alike.”
